1. Which of the following lobes of the brain is responsible for sensation, perception, and spatial reasoning?

Correct answer: C

Rationale: The parietal lobe is responsible for sensation, perception, and spatial reasoning. It plays a crucial role in processing sensory information, assisting in spatial orientation, and integrating various sensory inputs to create a comprehensive perception of the surrounding environment. The frontal lobe, although important for higher cognitive functions and motor skills, is not primarily responsible for sensation, perception, or spatial reasoning. The occipital lobe is mainly involved in visual processing, and the temporal lobe is primarily associated with auditory processing, memory, and emotions, making them incorrect choices for this question.

2. Which part of the nervous system is responsible for the “fight-or-flight” response?

Correct answer: C

Rationale: The sympathetic nervous system is responsible for the 'fight-or-flight' response, triggering the body's automatic response to a perceived threat or danger. This system initiates physiological changes like increased heart rate, dilated pupils, and the release of adrenaline, preparing the body to confront or escape the threat. The somatic nervous system (Choice A) controls voluntary movements, the parasympathetic nervous system (Choice B) is responsible for the 'rest and digest' response to promote relaxation and digestion, and the enteric nervous system (Choice D) regulates the gastrointestinal system. Therefore, they are not associated with the 'fight-or-flight' response.

3. Positron emission tomography (PET) scans utilize a key property of positrons for medical imaging. What is this property?

Correct answer: B

Rationale: Positron emission tomography (PET) scans utilize the property of positrons having a positive charge. Positrons are the antimatter counterpart of electrons, having the same mass but opposite charge. When a positron collides with an electron, they annihilate each other, producing gamma rays that can be detected by the PET scanner to create images of the body's internal structures and functions. Choice A is incorrect because positrons have the same mass as electrons. Choice C is incorrect as positrons are not extremely stable due to their tendency to annihilate when they encounter electrons. Choice D is incorrect as positrons exhibit different behavior than electrons due to their opposite charges.

4. As a car accelerates from rest, what happens to its kinetic energy and the work done on it?

Correct answer: A

Rationale: When a car accelerates from rest, its speed and kinetic energy increase. The work done on the car is what increases its kinetic energy, so both kinetic energy and work done increase simultaneously. Option A is correct because acceleration results in an increase in both kinetic energy and the work done on the car. Option B is incorrect because work done is required to increase kinetic energy during acceleration. Option C is incorrect as work done is directly related to the change in kinetic energy. Option D is incorrect as both kinetic energy and work done increase when the car accelerates.

5. Which type of cell division is responsible for growth and repair?

Correct answer: B

Rationale: Mitosis is the correct type of cell division responsible for growth and repair. During mitosis, a cell divides to produce two identical daughter cells, contributing to growth and tissue repair in multicellular organisms. Meiosis, on the other hand, is involved in the formation of gametes (sperm and egg cells) for sexual reproduction. Binary fission is a form of asexual reproduction in single-celled organisms, and osmosis is the movement of water molecules across a selectively permeable membrane. Therefore, choices A, C, and D are incorrect as they are not directly related to growth and repair in multicellular organisms.
